The key core equipment burner can adopt the technology of the automatic reducing anti-backfire burner shown in fig. 2, and the special curved surface of the burner head enables the waste gas outlet to change the flow direction under the action of Coanda Effect (Coanda Effect) or Coanda Effect, so that the waste gas outlet has the tendency to flow along with the surface of a convex object. When there is surface friction between the fluid and the surface of the object over which it flows, the flow rate of the fluid slows. According to the Bernoulli principle in fluid mechanics, a reduction in flow velocity causes the fluid to be attracted to the surface of the object and flow. Under the influence of the coanda effect, the waste gas can be better and faster mixed with air, and the high-efficiency decomposition of the waste gas is ensured.

Compared with the conventional fixed caliber combustor, the conventional combustor is designed to be a fixed outlet, when the difference between the maximum discharge design working condition and the minimum discharge working condition is large, the difference can be even dozens of times, and when the minimum flow is discharged, the exhaust gas outlet speed is lower than the tempering speed, so that the tempering and detonation phenomena occur.
